INSTALLATION KITS

LEG KIT

A leg kit which elevates the Unit six inches from the floor is available as P/N 311370--000. When installed, legs
relieve the user from the NSF International (NSF) requirements for sealing the Unit to the floor (USA only).

CASTER KIT

A caster kit (P/N 310340) is available which when installed, gives the Unit mobility.

THEORY OF OPERATION (see Figure 2)

A CO2cylinder delivers carbon dioxide (CO2) gas through adjustable CO2regulators to the product tanks. When
dispensing valve is opened, CO2pressure exerted upon product tank pushes product from tank, through unit
cooling coil, to dispensing valve resulting in a cold dispensed drink.

When unit power cord has been plugged into the electrical outlet and power switch on back of unit has been
positioned to ‘‘ON’’ (up) position, compressor, condenser fan motor, and agitator motor will start and begin
forming an ice bank. When a full ice bank has been formed, the compressor and condenser fan motor will stop
but agitator motor will continue to operate, circulating ice water bath in water tank. Water tank ice bank sensing
bulb will cycle compressor and condenser fan motor on and off as required to maintain full ice bank.

clearance:
Over top of Unit12 in.
Rear12 in.
Sides12 in.
FrontOpen

WARNING: All electrical wiring must conform to national and local electrical codes.

WARNING: CO2displaces oxygen. Strict attention must be observed in the prevention of
CO2(carbon dioxide) gas leaks in the entire CO2and soft drink system. If a CO2gas leak is

suspected, particularly in a small area, immediately ventilate the contaminated area before
attempting to repair the leak. Personnel exposed to high concentration of CO2gas will experience
tremors which are followed rapidly by loss of consciousness and suffocation.

2. Locate Unit near a grounded electrical outlet having a dedicated circuit fused at 20 amps (slow-blow).
Alternate protection using an equivalent HACR (US) circuit breaker may be used. Note: no other equipment
should be connected to this circuit.

3. Locate the Unit close to a water inlet supply with pressure and flow as given in the listing of Physical
Characteristics and Requirements.

7. Position unit power switch to ‘‘ON’’ (up). Compressor, condenser fan motor, and agitator motor will start
and begin forming an ice bank. When full ice bank has been formed, compressor and condenser fan motor
will stop but agitator motor will continue to operate circulating ice water bath in water tank. Water will
continue to drip from water tank overflow tube until full ice bank has been formed, then tube may be
removed from waste container and stored inside unit.

DRIP TRAY DRAIN HOSE CONNECTION (see Figure NO TAG)

NOTE: Drip tray hose routed to waste container is not recommended due to sanitiation and cleaning
problems. Connection of drain hose to permanent drain is recommended.

The drip tray, as provided, is self--contained and must be emptied periodically. If permanent drain is desired, cut
out center of drain connection on drip tray. Be sure to remove all plastic to open drain to its maximum inside
diameter preventing any rough edges which will trap dirt. Install DRIP TRAY (item 2) by inserting rear edge of
tray under lip of valve trim panel and lifting up until bottom tray supports are inserted in square holes provided in
front panel. Lock drip tray in place by a slight downward pressure. Connect drain hose below drip tray to drain
conection on drip tray. This drain hose runs to inside of unit and must be routed out through hole in back of unit.
Drain hose then must be routed to a waste container or routed to and connected to a permanent drain.

CONNECTING PRODUCT TANK SUPPLY LINES TO UNIT (see Figure 2)

NOTE: If 7/16--20 TANK QUICK DISCONNECTS are used, they may be connected directly to unit product
inlet lines if desired. If connecting 1/2--16 TANK QUICK DISCONNECTS (items 11 and 12) directly to unit
product inlet lines, REDUCER FITTINGS (item 5) and TAPERED GASKETS (item 6) must be used to
make connections.

All unit product inlet line internal connections have been made at the factory. Perform the following to connect
unit product inlet lines to product tank supply lines.

9 309989000

NOTE: The numbered unit product inlet lines are labeled to identify dispensing valve they serve. For
example: The line labeled ‘‘1’’ is connected to system that provides product to be dispensed from NO. 1
dispensing valve. (NO. 1 dispensing valve is valve on right side when facing front of unit.)

1. Install applicable ADAPTERS (item 4) in ends of unit product inlet lines.

NOTE: Allow additional line length if Unit is provided with casters.

2. Cut lengths of tubing to reach from product tank location to unit product inlet lines.

3. Install applicable SWIVEL NUTS and NIPPLES on both ends of lengths of cut tubing. Secure connections
with TUBING CLAMPS.

4. Connect made--up product tank supply lines to unit product inlet line adapter fittings.
